Considering the reference'character's, the

case, which of i the upright design, is formed of. the base 1, the uprightfsides 2, 2,

and the crossbar 4econnectingfthe upright sides at the'top'thereof. A continuous lami nated frame 3 is provided which extends at I the bassjend substantially parallel tothe side/2, and closely adjacent thereto; and

which extends across theba'se for about two thirds of its length toward the'treble end where it is thenpurved upwardly and later- V ally toward the: treble end to a point from which it f runs i substantially parallel "to but spaced from the side 2' to" a point at about two thirds of the height of the case Where said frame is curved toward the side 2 at the treble end ofithe case and extends parallel andadjacent 'to' the'side member 2 to I the top of the frame; At the "lower corner of the treble end of the" frame there is pro 'Vi'ded a fillerbarisfioflaminated construe-' tom thereof and, then transversely adjacent f and arallel to the'base lltoithe point where the rame 3 approaches saidbase member 1.

The filler bar 3, "together with e theframe 3'at the base end, makes a rim of'substanf tiallyU-shape. Abrace' bar 5" is buil'tinto Y thelaminated frame 3 at the bass end and extends from apoint midway thereof up-.

wardly and transversely for about one third of the distance across the backof thepiano and then on a line substantially parallel with th'e't op thereof to the treble side of the frame. An auxiliary brace bar 5 extends substa'n tially in line with-thatportion of. thebra'ce bar' 5 w'hich is at the treble end of'the-piano piano to a point about one third ofthe dis tance acrossthe piano where said auxiliary from the frame 3 at the bass .endflof the brace bar 5 joins-the bracebar 5."
